Final answer:
Nonreflective coatings are used in film projection and image capture to isolate the film and minimize light intensity over a range of angles, also finding use in car windows and sunglasses.
Step-by-step explanation:
The component used in film projection and image capture to isolate the film from vibration and tension is called a nonreflective coating. This coating plays a critical role in reducing the amount of light that is wasted by causing destructive interference, particularly when the thinnest layer is applied, as it helps to minimize the intensity of light over a broad range of incident angles. The effective utilization of nonreflective coatings is essential not only in filmmaking but also in other applications such as car windows and sunglasses.
